How can I pass the key when switching between pages?

I am trying to deal with a problem. Suppose we have tables A, B, and C. There is a relationship between table A and table B. In table B we store the key of table a. There is also a relationship between table B and table C. I fill in table B with the information in table C through a form page. A table called table D appeared with a new request. This table contains the grouped version of the data in table C. When any group in table C is selected, the data in this group should be inserted into table B one by one. I was able to insert using Action. But while inserting, I cannot see the newly added data on the screen because I do not have the key of table A. Because the relationship cannot be established correctly. The key remains blank. How can I resolve this situation? I should be able to pass the key of table A on page transition. How can I achieve this?

I believe you'll be better helping others to help you get better answers if you post your actual scenarios with examples and screenshots of your actual tables, rather than difficult-to-understand abstractions. Thank you!
